Methods and devices for prematurely terminating a transmission are provided. The method includes that a base station in a machine type communication (MTC) system receives a first data repeatedly uploaded by a terminal in the MTC system. Additionally, the base station determines whether all data blocks included in the first data are successfully demodulated. The first target number of times is a maximum number of times configured by the base station for the terminal for repeatedly uploading the first data. When determining that all the data blocks included in the first data are successfully demodulated before the total number of times of repeatedly uploading the first data reaches the first target number of times, target downlink control information (DCI) is transmitted to the terminal. The target DCI is configured to instruct the terminal to prematurely terminate uploading the first data to the base station.

7. The method of claim 6, wherein the target DCI further comprises a second target number of times, the second target number of times is a maximum number of times for repeatedly uploading the second data by the terminal, and the second target number of times is less than the first target number of times.
This invention relates to wireless communication systems, specifically methods for managing data transmission reliability in downlink control information (DCI) signaling. The problem addressed is ensuring efficient and reliable data transmission between a base station and a terminal device, particularly when retransmissions are required due to transmission failures. The method involves configuring a terminal device to receive downlink control information (DCI) that includes a first target number of retransmission attempts for a first data transmission. The terminal is also configured to receive a second target number of retransmission attempts for a second data transmission, where the second target number is less than the first. This differentiation allows the system to prioritize certain data transmissions by allocating more retransmission opportunities to higher-priority data while limiting retransmissions for lower-priority data, thereby optimizing network resources and reducing unnecessary signaling overhead. The DCI signaling includes control information that specifies the maximum number of times the terminal can retransmit the second data, ensuring that the terminal does not exceed this limit. This approach improves transmission efficiency by preventing excessive retransmissions of lower-priority data, which can congest the network and waste bandwidth. The method is particularly useful in scenarios where different types of data have varying levels of importance, such as in real-time applications or mission-critical communications.
